What is the effect of filling insulating glass with argon?
With the continuous improvement of people's living standards, the awareness of building energy conservation has gradually increased, and the insulation and thermal insulation performance of glass has gradually become the focus of attention.

Insulated glass has been widely used in the construction industry, can effectively reduce the heat transfer coefficient U value of the glass system and is a very economical and effective energy-saving method (the principle of hollow glass is to insert a layer of air with good insulation performance between the glass, which acts as a bottleneck and reduces the overall heat transfer coefficient).
Ways to improve the thermal insulation performance of insulating glass
(1) Use high-performance Low-E glass
(2) Increase the number of glass and cavity, such as increasing double-glass single cavity to three-glass two-cavity, or even four-glass three-cavity

(3) Change the gas composition in the cavity, such as filling with argon/krypton, argon-krypton mixture and other inert gases
(4) Extract the gas to make vacuum glass
(5) Increase the thickness of the cavity inside the insulating glass, etc.
The function of filling argon gas inside the hollow glass
(1) After filling with argon gas, it can reduce the pressure difference between the inside and outside, maintain pressure balance, and reduce glass explosion caused by pressure difference.
(2) After inflating with argon gas, the K value of the insulated glass can be effectively improved, the condensation of indoor side glass can be reduced, and the comfort level can be improved. That is, the inflated insulated glass is less prone to condensation and frost, but not inflating is not the direct cause of fogging.
(3) Due to the inherent characteristics of argon gas as an inert gas, it can slow down the thermal convection inside insulated glass and significantly improve its sound insulation and noise reduction effect, which can enhance the insulation and sound insulation of insulated glass.
(4) It can increase the strength of large-area insulating glass so that its middle will not collapse due to lack of support.
(5) Increase wind pressure resistance strength.
(6) Because it is filled with dry inert gas, the air with moisture inside the cavity can be replaced, keeping the environment inside the cavity drier and extending the service life of the molecular sieve inside the aluminum spacer frame.

(7) When using low radiation LOW-E glass or coated glass, the inert gas injected can protect the film layer, reduce the oxidation rate, and extend the service life of the coated glass.
